Biography
Antigonus was born in 382 BC to a Macedonian noble family, and he served as a general of Alexander the Great, commanding his 7,000 Greek allies at the Battle of the Granicus. In 333 BC, Alexander appointed Antigonus as Governor of Phrygia, and he defended Alexander's lines of supply and communication during his eastern campaigns. Following Alexander's death in 323 BC, Antigonus also inherited Pamphylia and Lycia, and he was made Strategos of Asia by Antipater following Perdiccas' death in 321 BC. Antigonus eliminated the remnants of Perdiccas' faction in two brilliant campaigns, and, after Antipater's death in 319 BC, Antigonus refused to acknowledge Polyperchon as the new regent of Macedon. He took control of the empire's eastern satrapies, Syria, and Asia Minor, forcing the Governor of Babylon, Seleucus, to form an alliance with Ptolemy I Soter, Lysimachus, and Cassander against Antigonus. Antigonus failed to conquer Rhodes in 306 BC, and he was struck and killed by a javelin at the Battle of Ipsus in 301 BC, leading to his son Demetrius I Poliorcetes inheriting his father's empire.
